Rory: I’m in form of my life

Rory McIlroy believes he is in the best form of his life as he seeks a third win in succession and second major title in the space of four weeks in the US PGA Championship.

McIlroy headed to Valhalla back on top of the world rankings for the first time since March 2013 after claiming his first World Golf Championship event in the Bridgestone Invitational on Sunday.

It is the third time the Open champion has taken top spot with a win, the first coming in the Honda Classic in March 2012 and the second later that year when he won the US PGA Championship by eight shots at Kiawah Island.
